Attack profile from CVSS 3.1 · CNA. Fix status from CNA and Red Hat. Impact type from CWE-835.
Summary
The JSONPath slice evaluator in json-glib, used by json_path_query(), can enter an infinite loop when given a slice expression with a negative step. A remote attacker without privileges or user interaction can supply such an expression to an application that evaluates attacker-controlled JSONPath, forcing it into a hang and causing a denial of service. The flaw is classified as CWE-835, a loop with an unreachable exit condition.
